I love games that play with concepts in physics and Manifold does just that by giving you tools to bend and defy gravity in an action-platformer. The goal is fairly simple - move your little man from the beginning of the level to the exit. Along the way, you'll find large anomalies, big blobs of gravity force, that you can collect and then shoot at spots within the game to help guide you past trecherous obstacles. Once you place an anomaly, you can use your mouse to change the direction of its gravity force, so that when you enter it, your little man gets pulled or pushed into a helpful direction.
